Therefore, the directional and positional terms used are intended to illustrate and facilitate understanding of this invention and are not intended to limit the scope of protection of this invention.

[0038] Example 1

[0039] like Figures 1 to 4 As shown, the first embodiment of the present invention includes a dust cleaning pipe 1, an air inlet pipe 2 and a rotating assembly. The rotating assembly includes a rotating joint 3 and a rotating pipe 4. The air inlet pipe 2 is connected to the rotating joint 3, and the rotating pipe 4 is connected to the dust cleaning pipe 1. The rotating pipe 4 and the rotating joint 3 are rotatably connected and the inner cavities of the two remain connected.

[0040] The dust cleaning pipe 1 is provided with a plurality of air injection holes 11 at intervals along the axial direction. One end of the air inlet pipe 2 is connected to an external air source and the other end is connected to a rotary joint 3 so that the air inlet pipe 2 is in communication with the dust cleaning pipe 1 .

[0041] It can be understood that clean air enters the cleaning pipe 1 through the air inlet pipe 2 and is then discharged from the air injection holes 11 on the cleaning pipe 1 to blow the materials on the inner wall of the cylinder to the bottom of the cylinder.

[0042] The rotating pipe 4 is connected to at least one set of symmetrically arranged dust cleaning pipes 1 located near the inner wall of the cylinder;

[0043] The dust cleaning pipe 1 includes a connecting pipe 12 and a blowing pipe 13. The left and right ends of the connecting pipe 12 are connected to the blowing pipe 13 and the rotating pipe 4 respectively. The blowing hole 11 is provided on the blowing pipe 13.

[0044] The opening direction of the air jet holes 11 forms an angle with the horizontal direction, and the angle ranges from 20° to 40°. It is understood that the opening directions of the air jet holes 11 on the left and right sides of the rotating tube 4 form an angle with the axial direction of the connecting tube 12, and the opening directions of the air jet holes 11 on both sides are opposite. When the air jet holes 11 rotate within the cylinder body, the directions of the gas ejected from the air jet holes 11 on both sides are at the same angle.

[0045] The rotary joint 3 includes a protective sleeve 31, a connecting pipe 32, and a connecting joint 33. One end of the connecting pipe 32 is connected to the connecting joint 33 and the other end is connected to the bearing of the rotary tube 4. The protective sleeve 31 is mounted on the connection between the connecting pipe 32 and the connecting joint 33. It can be understood that the upper end of the rotary joint 3 is connected to the intake pipe 2. The rotary joint 3 is connected to the rotary tube 4 via the connecting pipe 32. When the rotary tube 4 rotates and drives the dust removal pipe 1 to rotate within the cylinder body, the rotary joint 3 remains stationary, so that the intake pipe 2 remains stationary during operation of the present invention.

[0046] The bearing 34 is provided between the rotating tube 4 and the connecting tube 32.

[0047] The bearing 34 is sleeved on the outside of the connecting tube 32. The connecting tube 32 is provided with grooves at the upper and lower ends of the bearing 34 for the first limit block 35 and the second limit block 36 to engage with. The rotating tube 4 is provided with a protrusion for placing the bearing 34. The protrusion is provided at the lower end of the second limit block. The rotating tube 4 is provided with a threaded pressure plate 37, and the pressure plate 37 is provided at the upper end of the first limit block 35.

[0048] like Figures 5 to 8 As shown, this is the second embodiment of the present invention, which includes at least one set of symmetrically arranged scraper assemblies 5, a fixing assembly 6 and a fixing rod 7 arranged at the lower end of the rotating tube 4, and the fixing rod 7 extends downward to a position close to the bottom of the cylinder body. The two scraper assemblies 5 are fixedly connected to the fixing rod 7 through the fixing assembly 6.

[0049] It is understandable that, in the first embodiment, the clean gas is ejected through the air jet hole 11 to blow the material on the inner wall of the cylinder to the bottom of the cylinder. However, the material that has been adhering to the inner wall of the cylinder for a long time has formed into scale and is difficult to blow off. The scraper assembly 5 is used to easily scrape the attached materials on the inner wall of the cylinder. The scraper assembly 5 is gradually fixed to the fixed rod 7 by the fixing assembly 6. When the rotating tube 4 rotates, the scraper assembly 5 also rotates to scrape the attached materials on the inner wall of the cylinder.

[0050] The utility model adopts a method of respectively providing symmetrical scraper assemblies 5 on both sides of a fixing rod 7, which is convenient for installation and disassembly and convenient for modular production.

[0051] The scraper assembly 5 has a certain angle with the axis direction of the cleaning pipe 1. It can be understood that the scraper assembly 5 and the cleaning pipe 1 are not on the same horizontal line, and both the scraper assembly 5 and the cleaning pipe 1 rely on the rotating pipe 4 to complete the rotation process.

[0052] The scraper assembly 5 includes a cleaning member 51, a mounting plate 52, and a connecting rod 53. The cleaning member 51 is detachably mounted on the mounting plate 52, and the ends of the connecting rod 53 are fixedly connected to the mounting plate 52 and the fixing rod 7, respectively. It is understood that long-term use of the cleaning member 51 to scrape material from the inner wall of the cylinder will wear out the contact area between the cleaning member 51 and the inner wall of the cylinder. The detachable and replaceable cleaning member 51 allows the remaining parts of the scraper assembly 5, except for the cleaning member 51, to be reused.

[0053] The cleaning member 51 is a deformable structure, and the length of the scraper assembly 5 is adapted to the inner diameter of the cylinder. As can be understood, since the cylinder is shaped smaller at the top and larger at the bottom, the deformable structure of the cleaning member 51 allows the present invention to be smoothly installed within the cylinder and conform to the inner wall of the cylinder. The cleaning member 51 can be a brush, an integrated scraper, or other suitable structural member.

[0054] The fixing assembly 6 includes a fastening body and a first fastener 61. The fastening body is sleeved on the outside of the fixing rod 7 and is provided with a through hole 63 for the fixing rod 7 to pass through. The outside of the fastening body is provided with a plurality of first fastening holes 611 adapted to the first fastener 61. The first fastening holes 611 pass through the fastening body transversely and communicate with the through hole 63. It can be understood that first, the fixing rod 7 is passed through the through hole 63 on the fastening body to a certain position. When the utility model is in this position, the length of the scraper assembly 5 is adapted to the length of the inner wall of the cylinder body. At the same time, the first fastener 61 is inserted into the first fastening hole 611 to fix the fixing assembly 6 to the fixing rod 7.

[0055] The upper and lower ends of the fastening body are provided with shaft sleeves 65 that are sleeved on the outside of the fixing rod 7. The first fastening holes 611 are provided on the shaft sleeves 65. The fastening body is fixedly connected to the fixing rod 7 via the first fasteners 61. It can be understood that the first fastening holes 611 are provided on the shaft sleeves 65 at the upper and lower ends. The diameter of the shaft sleeves 65 is smaller than the diameter of the fastening body and larger than the diameter of the fixing rod 7. The first fasteners 61 pass through the first fastening holes 611 to limit the upper and lower positions of the fastening body, thereby securing the fixing assembly 6 to the fixing rod 7.

[0056] The fastening body is provided with a limiting groove 62 for placing and matching the connecting rod 53. It can be understood that placing the connecting rod 53 in the limiting groove 62 realizes that the connecting rod 53 is fixed to the fixing assembly 6, and indirectly realizes the fixed connection between the connecting rod 53 and the fixing rod 7.

[0057] The fastening body is provided with a second fastening member 64, and the fastening body comprises a set of symmetrically arranged first fastening portions 66 and second fastening portions 67. The first fastening portions 66 and second fastening portions 67 are provided with a plurality of second fastening holes 641 at relative positions that are adapted to the second fastening members 64. It is understood that the fastening body can be integrally formed or separately provided. The present utility model is provided with symmetrical fastening portions, the first fastening portions 66 and second fastening portions 67 being provided with limiting grooves 62 for placing the connecting rod 53. The second fastening member 64 is adapted to the second fastening holes 641 and sequentially passes through the first fastening portions 66 and second fastening portions 67 to achieve the fastening body fixing the connecting rod 53 in the limiting groove.

[0058] The connecting rod 53 is provided with a semicircular block 531 on one side close to the fixing rod 7. The semicircular blocks 531 on two symmetrically arranged connecting rods 53 are connected to form a block that is sleeved on the fixing rod 7. The first fastening portion 66 and the second fastening portion 67 are provided with a semicircular groove 532 that matches the semicircular block 531. It can be understood that the connection between the semicircular block 531 on the connecting rod 53 and the groove 532 allows the connecting rod 53 to be fixed to the fixing assembly 6, which is more effective.

[0059] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
